T0 is, whom, (it may conccrm Be it known that 1, CHARLES E. WiLLn'y, ecitizen of the United States, residing at Louisville, in the county ofJefiferson and. State of Kentucky, have invented certein new end usefulImprovements in Drilling Machinery; and do hereby declare the following;to be :t full, oleer, end exact description of the vention, snch willenable others skilled. in the ert to which it eppertsins to make and usethe same.

lily invention relates to improvements in lrilling-1nsehines, and moreparticularly to improvements in redial end semirsdisl drills,

My invention consists in mounting an eleciric or other motor ontheredial arm, heeci, or of the drill, and preferably between thesupporting-column end the drillspintlle, in driving therefrom gearing bywhich the spindle is rotstetl and the feed niechenisin opereteii,

lily invention consists, i'ni"ther,'in providing elevating mechanism bywhich the head iney he reisetl or lowered, said elevating mechanismbeing also driven from the motor in the head, in forming the pole-piecesof the motor as integral parts of the head, and in the men y noveldetails of combination, construction, and arrangement of the per-ts.

The objects of my invention are to simplify the structure of drillingmachinery, and particularly of radial and seinirsiliel drill-presses, todispense with the devices ordinarily employed for transmitting motionfrom a counter-shaft occupy i'ng it fixed oosi tion to the movable heador cerrisge of the machine, to evoirl theme of belts, splineotransmitting-shafts, and the 1'3 power is orinerily communieetecl GO .6mechanism of the movable he d, o e 6 l and to meke'the mechanism ofilill ple, compact, and self-conteineol, it easy to start end stop-thefirili, to Vet! speed, to raise or lower its heed, orito is its head toone side or the other at will, redial and sernirediel drills areordinarily co: structed power is commnni'ceteil i c i e co ,4 ter-sheftoccupying a iizecl position with re spect to the machine and often orusua ly placed at the base of the-machine to spinLlle-driving andautomatic feeo. mes ism through the medium of belts or s netl shafts thelike. To permit the raising; and of the heed, to permit it to he swung);from one side to the other, end, case of redial drill, to the heeii tohemoved in end ont the radial arm involves the use of transmittingmechanism of considerable complication for the transmitting of "notioniron: the counter-shaft ebove ineetioneil to the drill-seinrlle end itsfeeding devices. All of this complication be overcome by mounting atprime motor directly in or on the (irill'cerrying heed of the machine,end motor may he so mounted end. conveniently meshed pieced out the Wayand protected f om njury by locating: the motor in the (lrv l-eerriieefil of the .cliine. By so doing all oi the complication 'ncicient tothe transmission power from a ixetl conntensheft to e verticelly,laterally, and often radially movable dr "1 heel or cerriege is entirelyevoiilezl. This is l -:.lo in the machine herein. ill nstrstetl end l6-scribed.

in the machine herein illnstretecl and i6- scribed, the motor shown notonly as carried by the heeoi, but as inclosccl Within same. This isadvantageous as protecting the motor from injury, as providing structureof the greetest simplicity least weight. Further, the inotoris arrangedwith its drive or erinetnre shaft in e horizontal plane and locatedbetween the drill-spindle and the support. This is an important feetnreof the invention. The weight of the motor is disposed nearest the pointof support, and hence the least strein is exerted on the head. Theworking or movable parts of the motor, together with the heaviestportion of J the wearing, revolve noon horizontal beerii.

A i13LQ,-Zl-Wl166l -11 is epiined; to el eit 4:0 encl isprovided with a cone 42, lying Within a conioel recess in the bevehgear39 and forming a oone-olutch, by which gear 39 may be placed.

The ooeetroetion liere described. is eulostentielly commonly employedfor throw- 'l 'iflj in out the en toii'ieiio feetl of, 3, e; .iie-tool.

The meehenism above deeoribecl comprises til meclmnisiii for rotatingthe drillepimlle, i'or automatically feeding; the some both by power andby hand, and for quickly raising; and lowering the same. I have alsoprovided mechanism. for automatically raising or low-- ering the 5. Uponthe lower-end of the 60, ca rying tlie cone-pulley 33 and gear 32, thereis a. gear 61, intermeehing; with e 62. (Shown in dotted linee in Fig.2.) Gear 62 iiiterinesliee with another gear 68, which letter gearintermeeliee with a gear 64., which forms a part of e screw-nut surroundan. elevating-screw (35, mounted alongside of the column 2 Gears 62 and63 are carried e bracket 66., pivoted concentrically on a. screw55,Wl1il1 bracket is provided with a. lion- (lle 67, by which it maybemoved. By moving" said lizmdle inward out of mesh with gear 61, end bymoving sold handle still farther gear 63 may be brought into mesh withgear 61, gear 62 being then an idler. "When. gear 62 is in meal: withrem? 61 if the motor be operetecl tlio l aeecl 5 will be shaft 40 or maygear 62 may be thrown tion between gear 31 and moved in one direction,and if gear 63 be in mesh, the motor being operated, the head will bemoved in the otherdirection.

Upon one side of the head is a startingrheostat 68, and upon the otherside of the head in the vicinity of the column 2 is a speedregulatingrheostat 69.

In the operation of this drill when the armature-shaft revolves power iscommunicated through the back gears 21 and 23 to the shaft 19 ordirectly to said shaft if gears 21 and 23 be out of operation, and fromshaft 19 power is communicated through bevel-gears 27 and 28 to shaft 29and pinion 80. From pinion 30 motion is transmitted to gear 31 andthence to the drill-spindle 6. The revolution of the drill-spindle isindependent of longitudinal motion thereof, because of the splineconnecspindle 6. From pinion 30 motion is also transmitted to gear 32and thencerthrough the cone-pulleys 33 and 35 to shaft 34; gears 36 and37, bevel-pinion 38, and bevel-gear 39. If the cone 42 of the feed-wheel41 be in contact with the conical recess of gear 39, then thedrill-spindle is fed downward slowly and automatically by the pinion 50and rack 51, pinion 50 being driven from hand-wl1eel41, worm shaft 40,worm 43, worm-wheel 44, friction-cone 46, and shaft 45.

he automatic feed may be stopped at any time by turning the nut 42 Thedrill may be fed in either hand when the automatic feed is not inoperalion by means of hand-wheel 41.

For quick adjustment of the position of the drill or for quickly raisingthe same the clamping-nut 48 may be relieved and the required adjustmentobtained by turning the handles 47. \Vhen the clamping-nut 48 is incontact with the wheel 44, the drill is held stationary, except as itmay be moved in either direction by the automatic feed or by turning thewheel 41 by hand, owing to the self-locking action. of the worm 43 andthe worm-wheel 44.

To raise or lower the head 5, the clampingnuts by which said head isclamped to the column 2 are first relaxed, and then the handie 67 ismoved in the proper direction, so as to bring gear 62 or gear (53, asthe case may be, into mesh with gear (31.

Having thus completely described my invention, what Iclaim, and desireto secure by Letters Patent, is-

1. In a drill, the combination with a support, a head movably securedthereto, and a revoluble spindle carried by said head, of a motormounted within said head, and carried 1 thereby, the drive-shaft of saidmotor being arranged horizontally and located between said support andsaid revoluble spindle, a pinion carried by said drive-shaft, backgearin-g driven by said pinion, a bevel-gear connected to said backgearing, a vertical shaft, a bevel-gear on said vertical shaft anddriven by first-mentioned bevel-gear, a pinion on said vertical shaft,and a gear-wheel having a splined connection with the said revolublespindle, and in engagement with said pinion.
